Builders FirstSource provides lumber and building supplies. The customer service is outstanding, with staff described as patient, thorough, knowledgeable, and helpful. In one instance, an employee took a significant amount of time to discuss a deck project, even knowing the caller might not make a purchase. This help prevented a customer from ordering the wrong product by explaining wood sizing, which other lumber places and a contractor did not do. The service was a lifesaver. For other projects, matching materials like molding is quick and straightforward. Employees can immediately identify matches from samples. The location on Whitestone is correct, though online directions can be misleading. Customers should look for the large "Will Call" sign. The process is efficient. Staff members are friendly and awesome, often greeting customers with a smile. The experience encourages customers to return for future building supply needs.
